No Washing of Vehicles Sign

I found this sign at the foot of the grotto in Paraiso ni Anton in Pagudpud, Ilocos Norte. I was reading the sign and noticed that they were quite specific in a number of things such as “No Washing of Vehicles” and “No Dumping of Garbage and Dead Animals”. I find it peculiar and funny at the same time. 😀 I was wondering if there were people who were penalized for washing vehicles or for dumping dead animals there since I really cannot dig the possibility of people washing their vehicles in front of a tourist spot and even the dumping of dead animals :D.
